Can you see them when you do cat /proc/dasd/devices ? If not than first bring them online (chccwdev -e 0.0.XXXX) and then check again. If they are there, than you are ready to do a low level format with dasdfmt /dev/dasdX (/proc/dasd/devices will tell you which dasdX is that). After that, create partitions (or not if you don’t want to) with fdasd /dev/dasdX Later you can create LVM (or not if you don’t want to) with pvcreate, vgcreate, lvcreate. Last step is creating a filesystem with mkfs.ext4 (or ext3) on a new partition or logical volume. And now, you can mount it.
But you have to know that at this point you are also rewriting cylinder 0 of this DASD (if it is really attached) so it’s label will change. Let us know if you need more details Grzegorz Powiedziuk > On Aug 6, 2015, at 3:04 PM, Cameron Seay <cws...@gmail.com> wrote: > > of course Debian can't see it until it's in a Linux > filesystem. We don't know how to format it while in Debian. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
